The two main fitting ends II and I2 are 1ocated in alignment with eachother and form together a straight pipe section which is placed into themain line 8 on the installation of the valve in a manner 'to bedescribed further below. The two side iitting ends I3 and I4 are bentaway from this pipe section so as to stand at right angles therewith andin parallel with each other.

The valve chamber I5 is positioned eccentrically between the ends of thepipe section Il, I2, so that the tting end I I is longer than the shortfitting end i2 as appears from the drawing. Furthermore, the valvechamber is positioned midway between the pipe section II, I2 and theside fitting ends I3, Ill as shown, partitioned walls I5 and II beingprovided to complete the separation of the respective tting ends.

The wall of the conical valve chamber I5 is provided with four ports I8,I9, and 2| lying in the same plane and opening into the fitting ends II,I2, I3 and I 4 respectively. A closely tting conical plug 22 isrotatably mounted in the chamber I5 closing same at the top and bottom.The plug is provided with a square head 23 at its wider end adapted toreceive a wrench or key to turn the plug, and with a threaded portion 23at its smaller end receiving a nut 25, which engages a washer 26 restingon the flat end of the chamber wall and keeping the plug tightly locatedin the valve chamber. The plug has two grooves cut away in its body inthe same plane as the valve ports, so that a bridge portion 2 is formedwhich divides the interior of the valve chamber I5 into two passagewaysconnecting either ports I8 and 20 on one side and ports I9 and 2l on theother side (see Fig. 4) or connecting ports I8 and I9 and ports 20 and2|, depending on the position of the plug. Thus, a two-way valve isobtained which may either directly connect the main fitting ends I I andI2 in the main tting line, bypassing the detour 2, 3, or cut the detourinto the main line.

To facilitate the installation of the valve, the

Vstraight pipe section II, I2 to be inserted in the main pipe line isprovided with two spaced indexing projections 29 cast into the valvebody to indicate the length of pipe to be cut out from the main line.These projections may be accompanied by an engraved text 30 such as Cutpipe here. In Fig. 4 the cut pipe ends of the main pipe 8 so obtainedare designated by 38, 39 respectively.

As shown, the fitting end I2 and also the fitting ends I3 and I4 areprovided with pipe stops 3I projecting from their inner wall at asuitable distance from their open ends. These fitting ends are kept asshort as is constructionally advisable so as to save material andWeight. The fitting end II, however, is somewhat longer than the Y endI2 and has no inner pipe stop. This larger end is to be entered firstinto the cut main line and may be provided with Aa suitable marking 32to indicate this, such as the engraved words Enter this end first- Thefitting end II has K such a length that when it is Vfully entered in thermain pipe line after the required length of pipe I I still surroundsthe other cut pipe end 38 overY a sufficient length to insure adependable coupling to be made.

The fitting ends II and I2 are provided with suitable plain end pipecoupling means so that the cut pipe ends 38, 39 of the main line neednot be threaded or worked. Preferably the side fitting Yends I3 and IIIare provided with the same kind of coupling means as the main fittingends.

In the embodiment shown these coupling means comprise an annular gasket33 bevelled at one end, a gasket retainer cup 34 and a hexagonal end nut35. The fitting end has a threaded end portion 3B ofegreater diameteradapted to receive the nut 35, which end portion encloses a gasketrecess adapted to receive the bevelled gasket 33. When the end nut 35 isdrawn up it engages the gasket retainer 34 partially enclosing thegasket 33 and thereby presses the latter into the gasket recess forsealing engagement with the end portion 36 and the outer wall of thepipe end introduced in the fitting end. To provide for some deflectionof the pipe ends with respect to the valve tting ends, the innerdiameter of the tting ends is made somewhat larger than the outerdiameter of the pipe and an inwardly projecting annular ridge 31 isprovided to properly bound the gasket recess on its inner side.

To install the valve according to the invention in an existing pipeline, first a piece of pipe is out out from the main line 8 having thesame measured length as the distance between the two markings 29 wherebythe two plain cut pipe ends 38 and 39 are obtained. The loose nuts 35,gasket retainers 34 and gaskets 33 of the main fitting ends II and I2are then in this sequence placed around these two cut pipe ends and thelong tting end II marked Enter this end rst is moved so far around oneof these cut pipe ends, e. g. the end 38, until the fitting end I2 canbe swung in alignment with the opposite cut pipe end 33. In thisposition the fitting end II is fully entered, the cut pipe end 33approximately abutting the wall of the valve chamber I5. The fitting endI2 may now be moved back over the pipe end 39 until stopped by the pipestop 3l, in which position the fitting end II surrounds the pipe end 38over approximately the same length as the fitting end I2 the pipe end39. Lastly, the couplings are assembled on the fitting ends II and I2and the nuts 35 tightened, whereafter the side pipe lines 2 and 3 can becoupled to the fitting ends I3 and I4 in the known manner.

It will be clear from the foregoing that the new valve on account of theplain end coupling means and the other features described, can beinstalled Very quickly and easily in a main line, making only a shortinterruption of the water supply necessary. The valve is of compactconstruction, the provision of a short and a longer main fitting endmaking it possible to save some material in the body casting and alsoallowing a shorter piece to be cut out of the main line than would berequired if the ends were of the same length.

Although the invention has been described in conjunction with a specialembodiment thereof, it will be understood that various modifications inform and construction or possibly within the the scope of the followingclaims.
